Answer 2

Answer:

Principal = 1250

Step-by-step explanation:

Given : CI = 102

rate 4%,

time 2 years

To find :- Principal = ?

C.I = P [ 1 + $\frac{r}{100}$ ]ⁿ - P

A= P [ 1 + $\frac{4}{100}$]²

A= P [ 1 + $\frac{1}{25}$]²

A= P [ $\frac{26}{25}$ ˣ  $\frac{26}{25}$ ]

A = $\frac{676}{625}$P

C.I = Amount - Principal

102 =  $\frac{676}{625}$P - P

$\frac{51}{625}$P = 102

P = 102×625 ÷ 51

P = 63,750 ÷ 51

P = 1250
